One of the most detailed “maps” of our galaxy ever compiled has been released.
“Seen in visible light, these regions of the Universe are often dark and obscured due to the dust,” the European Southern Observatory’s website explains. “But they shine brightly in the millimetre and submillimetre part of the spectrum. This wavelength range is also ideal for studying some of the earliest and most distant galaxies in the Universe, whose light has been redshifted into these longer wavelengths.”
The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) compiled the images by studying submillimeter wavelengths, which are between infrared light waves and radio waves.
